Problem of building and designing on semi rocky soils (lower Permian soils) is problematic for many regions. In particular, in Russia the problems of building on semirocky soils are not given clearly enough in national construction norms and standards. Approximate calculation methods of end-bearing pile point resistance on weak fissured semi rocky soils, based on SP 24.13330.2011 "Pile foundations" are presented. Some results of static load test are confirms the approximate calculation method results. This method is recommended to use in engineering practice.
This paper reviews a question of tank construction based on a plate foundation with weak and heterogeneous soils as a subbase. The authors propose to use their method for determining the subbase characteristics by a cone penetration test. A program that allows to get a digital three-dimensional estimated model of soil resistance is developed to make the calculations. Technical and economic parameters of designing the foundation by using the proposed method and by using the traditional research method are compared.
Optimization models of heat treatment process of masonry in the winter due to a stationary heating system constructed buildings in oil production industry
In this work we propose a new method of the heat treatment of the masonry in the winter and the algorithm for masonry work-flow management that reduces overall the building construction time. There are developed software under the proposed algorithm, calculating the heat treatment of masonry in winter conditions with stationary heating system. This software automates the thermal engineering calculations and the necessary organizational and technological parameters of the organization of building flow, which greatly optimizes the performance of the project.
This paper describes new technologies of construction and repair of gas facilities, based on the use of explosive energy. The technologies were developed in Ltd. “Gazprom transgaz Samara”. It is shown that the use of alternative technologies can improve labor productivity, reduce the amount of heavy equipment used in the construction of gas pipelines. Technology utilization can also improve environmental and industrial safety. Innovative technologies are non-competitive in some cases, such as dismantling of large concrete foundations, partial dismantling of the foundations for the installation of new pumping units, eliminating the roll o flight poles, lightning rods and transmission towers, replacement, rapid dismantling of pipelines with maximum wall thickness.
This article describes the currently used technologies for loosening of frozen ground including permafrost. Currently there is no effective technology. The new technology of loosening of frozen ground is described. Several types of powerful linear explosive sources including the conversion type are offered for the successful application of this technology. A universal underground pile driver of linear charges is developed. An important factor here is a simple manufacturing technology of liquid explosives on site. This technology and pile drive of linear charges passed expert examination of industrial safety and approved for constant use by The Federal Service for Environmental, Technological, and Nuclear Supervision of Russia. The results of industrial testing are shown.
